获取使用javafx播放的mp3文件 [英] Getting a mp3 file to play using javafx

问题描述

我已经花了几个小时，查看如何在日食中获得某种形式的音频，并且每一步都遇到麻烦。目前我有一些应该工作的东西，但是我收到一个错误：

I have spent hours today looking up how to get some form of audio in eclipse and have had trouble every step of the way. Currently I have something that should work but I get an error:

线程main中的异常java.lang.IllegalArgumentException：预期的文件名作为参数
com.sun.javafx.css.parser.Css2Bin.main（Css2Bin.java:44）

Exception in thread "main" java.lang.IllegalArgumentException: expected file name as argument at com.sun.javafx.css.parser.Css2Bin.main(Css2Bin.java:44)

我已经从有人工作的人基本上复制了这个。我想说，FX库是添加在哪里应该的。我知道这不是幻想，但我只是在尝试基础。

I have basically copied this from someone who had it working. I would like to say that the FX lib is added where it should be. I know this isn't fancy but I was just trying the basics.

package b;
import java.io.File;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
public class test {

    public static void main(String[] args){
    String uriString = new File("C:\\Users\\Mike\\workspace\\b\\src\\hero.mp3").toURI().toString()
    MediaPlayer player = new MediaPlayer( new Media(uriString));
    player.play();
}}

我还尝试了许多不同的路径名，以防不正确幸运的是，我也试图复制并粘贴我在eclipse中获得的路径名，转到属性例如：/b/src/hero.mp3。帮助不胜感激，让我脱离这个噩梦。

I have also tried many different path names in case it was wrong with no luck, I also just tried to copy and paste the path name that i got in eclipse by going to properties ex: /b/src/hero.mp3. Help would be appreciated to get me out of this nightmare.

推荐答案

位于工作区外部的文件应包含在 file：// 前缀。演示功能的简单示例是

The files located outside the workspace should be included with file:// prefix. A simple example demonstrating the functionality is

public class Reproductor extends Application {

    public static void main(String[] args) {
        launch(args); 
    }

   @Override
   public void start(Stage stage) throws Exception {
       Media media = new Media("file:///Movies/test.mp3"); //replace /Movies/test.mp3 with your file
       MediaPlayer player = new MediaPlayer(media); 
       player.play();
   }  
 }
